I have an issue with some irregularly sized screens displaying my videos full screen. My screens are the following resolutions and aspect ratios. 

 

1920 x 1200 with 8:3 aspect ratio

1920 x 720 with 16:10 aspect ratio

A little bit more about my project..

I have 3 screens that all run videos that play off of each other. They're connected through a router and all 3 restart when the first BrightSign video restarts. Slave and master scenario.

 

What I've tried..

I've tried setting my BrightWall configuration to 100% width & 100% height. This doesn't produce a video wall at all. Just a black screen.

The zones are all "set to scale."

I've tried setting the presentation properties to "stretched" with a view mode of "scale to fill". Although, when I do this it wont allow me to add more than one video.

Any ideas? Lil help anyone?

  So I just looked at an older file I have that was working on these screens. I tried reverse engineering it and set the resolution to 1280x720x60p. Now I'm getting a garbled screen like the image below. Does this mean anything to anybody?

  That garbled display looks like the screen can't understand the signal.

  The core issue is that your screens are displaying the input pixels as non-square output.

  Essentially you need to treat this like anamorphic DVDs where the output will be stretched.

  1920x1200 in square pixels would normally be 16:10 aspect, but your 1920x1200 screen is stretching it to displays it as 8:3 or effectively 3200x1200 in square pixels.
  So in order to use a square-pixel video, it would need to have a 0.6x horizontal squeeze applied to compensate for the display's 1.667x horizontal stretch, displayed in a 1920x1200 zone.
  In other words, square pixel video needs to be disproportionately scaled to 3200x1200 (or 1920x720 if your player cannot decode 4K, but then you'll lose both horizontal and vertical precision on output) and that video displayed in a 1920x1200 zone with View Mode set to Scale to Fill, with the player set to a 1920x1200 output.

  Your 1920x720 display would be 8:3 in square pixels, but it squeezes to 16:10 or effectively 1152x720 in square pixels.
  So in order to use square-pixel video here, it would need to have a 1.667x horizontal stretch applied to compensate for the displays 0.6x horizontal squeeze.  To further complicate things, 1920x720 is not a standard output resolution.
  So, square pixel video needs to be disproportionately scaled to 1152x720 and that video displayed in a 1920x720 zone with View Mode set to Scale to Fill, with the player set to (likely) a 1920x1080 output .

  If the above doesn't make sense, open a support ticket and send us download links to your media and presentation files along with a system diagram or further description of how this is all being put together.
